Hey, GFX, rest easy; Acoustic Guitar is a pretty good magazine that a couple of students of mine loan me, once in awhile. But if your kid is into other kinds of music (blues, rock, jazz. . .), you really can't beat Guitar Player Magazine that covers all kinds of music, from classical to rock, both electric and acoustic, and has been around since about '67 or so. Acoustic Guitar does have online articles and lessons, and I suspect that Guitar Player also does, although I'm not sure about them. . .
